You might find it interesting sometime to watch the end of "Saving Private Ryan". The US sniper, PVT Jackson played by Barry Pepper, in the church steeple in the defense of the bridge at Romelle shoots lefty. Even though he is just an actor, and who knows what his real-life training is, he is quick and smooth while using his right handed '03 to pick off a double hand full of attacking Germans. He didn't have to deal with much recoil if they even used blanks but he does a very credible job making it believable.
